The purpose of this study was to identify the impact the Girls on the Run (GOTR) program had on the New Castle County, Delaware, third, fourth, and fifth grade girls who participated in the spring 2011 season. Specifically, this study examined short-term changes in the participants as they related to self-esteem, body image, physical activity commitment, and physical activity frequency. The design of the study was non-experimental, one group, pre and post intervention using a Likert-type paper pencil assessment tool (n=355). Two tailed paired sample t-tests were used to assess the changes (p < 0.05). This study found a statistical significance in participants' self-esteem (p = 0.001), body size satisfaction (p = 0.001), and PA frequency (p = 0.016). A statistical significance was not found in the participants' PA commitment (p > 0.05). As a result, this study found that participation in the NCC, DE GOTR Spring 2011 program resulted in short-term statistically significant improvement in ones' self-esteem, body size satisfaction, and physical activity frequency.
